Letters Patent No. 90,7 52, dated J une 1, 1869.

nvxPRovt-my HULLINGMAQ'HINE.

I The Schedule referred to in these Letters Patent and making part of the same.

, ings, forming partof this specification.

This invention relates to improvements in hullingmachines, such as are used forhnlling corn, barley, rice, and other grains, the object of which is yto provide a more simple and economical machine than those now in use.

, In theaccompanying drawings- Figure 1 represents an elevation, partly in section, of my improved machine; and

Figure2 represents a horizontal section, taken on the line a: x of fig. l. f

Similar-'letters of reference indicate corresponding parts.

A represents a hollow vertical cylinder, preferably made of cast-iron, and chilled, and grooved on the inner surface, as represented at B.

G represents av spiral-duted shaft-,- provided with sharpened pins, D, projecting from its several faces,

at aboutthe same distance radially as the corners E,

of the shaft, and the latter are notched, as shown at F, for a portion of their length.

The grain to be operated upon is spouted in at the top ofthe cylinder, and is delivered at the gate G, af-

ter having been operated upon. 1

This arrangement provides a very cheap machine, which requires but a small amount of power for working it.

I am aware of the patent granted to Alfred `and William J. Duvall, January 9, 1838, in which' is shown aplaiu cylinder, provided, upon its periphery, with spirally-arran ged teeth, andthe patent of B. Bridendolph, August 22, 18.54, which shows a spirally-grooved cylinder, having its edges serrated; but neither of these features constitutes my invention, and I do not, therefore, claim them.

`Vihat I doclaim as new, and desire to secure by Letters Patent,`is

'Ihe combination of the sharpened radial pins D with spirally-uted shaft O, and longitudinally-grooved cylinder A, said pinsbengarranged in spiral lines, as shown, for the purpose speciied. l
